Can a triangle be formed with 4cm 8cm and 12cm

1 answer:

7 0

No. 4^2 + 8^2 or 16 + 64 is 80, and the hypotenuse, 12 (144) is not 80.

Answer:

$\large\boxed{b=\sqrt{95}}$

Step-by-step explanation:

Use the Pyhagorean theorem:

$leg^2+leg^2=hypotenuse^2$

We have

$leg=b,\ leg=7,\ hypotenuse=12$

Substitute:

$b^2+7^2=12^2$

$b^2+49=144$ <em>subtract 49 from both sides</em>

$b^2=95\to b=\sqrt{95}$
